Abstract: The invention discloses a method and a system for achieving timely updating of client configuration. The method includes steps: after the client initiates any request to the server, receiving a response message fed back by the server; and obtaining a response header data containing client configuration information from the response message. The response header data includes configuration header data and version header data. Based on the configuration header data, it is determined whether there is an update in the client configuration stored at the server. If there is an update, the configuration at the client is updated based on the version header data. The invention can achieve timely updating of important configurations of the client based on frequent HTTP requests between the client and the server.

Abstract: Embodiments herein may relate to, for example, a method performed by a first network node for handling a testing process associated with a third network node in a wireless communications network. The first network node obtains an instance identity of an updated or initiated third network node; and stores one or more identities of one or more UEs to be used during the testing process mapped to the obtained instance identity. Upon detection of a session establishment of a UE, the first network node checks whether an identity of the UE matches the stored one or more identities of the one or more UEs; and, with the proviso that the identity of the UE matches one of the stored one or more identities of the one or more UEs, the first network node initiates a NF discovery towards a second network node using the instance identity mapped to the matched one identity.

Abstract: An ultra-narrow linewidth polarization maintaining Brillouin fiber laser allows for operation in the fundamental longitudinal mode for extended fiber cavity lengths. Mode hops can be suppressed via ultra-high precision temperature control of the Brillouin fiber laser via dual polarization operation enabled via injection of two pump signals along two polarizations directions and high-bandwidth stabilization of an ensuing polarization beat signal involving amplitude control of at least one of those pump signals. Multi-mode operation of the Brillouin fiber laser can be suppressed via the inclusion of large cavity losses into the Brillouin oscillator or the utilization of coupled-cavity Brillouin oscillators. By operating the coupled cavity Brillouin oscillators near the exceptional point, the power contrast between the fundamental longitudinal mode and any higher-order longitudinal modes can be increased at an optimum pump power above a Brillouin threshold.
